Browser vulns and botnets head threat list

Shifting SANS

Common Topics

Security experts have looked into the crystal ball to predict the cyber attacks most likely to cause substantial damage this year.

The resulting list (below), drawn together by 12 security experts under the auspices of the SANS Institute, is based on an analysis of emerging attack patterns. Two of the resulting predictions - malware on consumer devices and web application security exploits - have already come true in the early days of 2008, evidence that that the run down is closer to the mark than other security predictions.

As is often the case browser exploit came out as the top threat in the run down but the risk is evolving. Web site attacks have migrated from simple exploits to more sophisticated attacks based on scripts that cycle through multiple exploits to yet more sophisticated attacks featuring packaged modules. One of the latest such modules, mpack, produces a claimed 10-25 per cent success rate in infecting surfers.

Attackers are actively placing exploit code on popular, trusted web sites where users have an expectation of security. Placing better attack tools on trusted sites is giving attackers a huge advantage over the unwary public. Meanwhile attackers have broadened the scope of the vulnerabilities they target to encompass components, such as Flash and QuickTime, that are not automatically patched when the browser is patched.

Evolution in existing threats - including stealthier botnet control techniques and more subtle social engineering approaches in phishing attacks - is a theme that runs through the whole list.

Cyber espionage efforts by well resourced organisations looking to extract large amounts of data – particularly using targeted phishing.

An increase in mobile phone threats, especially against iPhones and Android-based phones.

Insider attacks

Advanced identity theft from persistent bots. Malicious agents that stay on compromised machines for months will be able to gather enough data to enable extortion attempts (against people who surf child porn sites, for example) and advanced identify theft attempts where criminals have enough data to pass basic security checks.

Increasingly malicious spyware

Web application security exploits

Increasingly sophisticated social engineering including blending phishing with VoIP and event phishing. For example, a blended attack may include an inbound email, apparently being sent by a credit card company, asks recipients to "re-authorise" their credit cards by calling a 1-800 number. The number leads them (via VoIP) to an automated system in a foreign country that, quite convincingly, asks that they key in their credit card number, CVV, and expiration date.
